crypto/internal/nistec: golang: Timing sidechannel for P-256 on ppc64le in crypto/internal/nistec

A flaw was found in the Golang crypto/internal/nistec package. Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture. Considering how this function is used, this leaka...

CLSA-2025-1749479602 gnutls: Fix of 3 CVEs

Keep the broken pkcs11 tests disabled. - Added CVE-2024-0567 PoC test. - CVE-2023-5981-pre1: improve level of randomness for each operations, always use gnutlsswitchlibstate for pk wrappers. - CVE-2023-5981-pre2: add constant time/cache operations to prevent or minimaze timining or cache side...

Securing Unbounded Differential Privacy against Timing Attacks

Recent works have started to theoretically investigate how we can protect differentially private programs against timing attacks, by making the joint distribution the output and the runtime differentially private JOT-DP. However, the existing approaches to JOT-DP have some limitations, particular...

NewStart CGSL MAIN 7.02 : tongsuo Multiple Vulnerabilities (NS-SA-2025-0075)

The remote NewStart CGSL host, running version MAIN 7.02, has tongsuo packages installed that are affected by multiple vulnerabilities: - Use of the low-level GF2^m elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes...

Timing Side-channel Attack

signxml is vulnerable to a Timing side-channel attack. The vulnerability is due to information leakage during HMAC comparison when requirex509=False and hmackey is used, allowing attackers to infer the correct HMAC...

GHSA-GMHF-GG8W-JW42 SignXML's signature verification with HMAC is vulnerable to a timing attack

When verifying signatures with X509 certificate validation turned off and HMAC shared secret set signxml.XMLVerifier.verifyrequirex509=False, hmackey=..., prior versions of SignXML are vulnerable to a potential timing attack. The verifier may leak information about the correct HMAC when comparing...
